To all whom it may concern: I

Be it known that I, ARENT AUGEs-TAD, citizen of Norway, residing atMarka Brandbu Station, Hadeland, Norway, have invented new and usefulImprovements in Inlay-Soles for the Prevention'of the Development ofGalls, of which the following is a specification,

The present invention relates to unprovements in inlay soles for bootsor shoes, the object of the inventionbeing to provide a device of thischaracter which will prevent the chafing of the feet of the wearer andthereby avoid the formation of galls or blisters.

The drawing accompanying and forming part of this specificationillustrates in side elevation, partly in section, an embodiment of theinvention.

It stands to reason that boots which are manufactured wholesale veryseldom fit the foot so exactly that when the wearer is walking they canfollow the movements of the foot with accuracy. This is especially thecase when heavy laced boots such as are used by workmen and soldiers areworn.

With such boots it is impossible to prevent the foot-under its effortsto bend the sole and the bootfrom moving to a certain extent within theboot or shoe, the result of which movement is that the heel of the footrubs against the heel of the boot, thereby causing the formation ofblisters.

The object of the present inventlon is to provide a device by means ofwhich the in-' evitable movement of the foot with relation to the bootshall not produce any injury or discomfort to the wearer. This isaccomplished by fixing the position of the foot within the boot so thata predetermined dis tance is maintained between the heel and toe of thefoot and the heel and toe of the boot, whereby the foot may move withinthe boot without chafing. To obtain this result a suitable intermediatepart is placed between the foot and the boot, consisting of a doubleinlay sole, one part of which is adapted-exactly to fit the bottom ofthe boot or shoe and the other part of which comprises means forsecuring it to the foot and preferably has the form,0f ,a, heel-cap withfastening.

belts or laces. 7

.Referring to theldrawing, 1 is the lower by-sole, which is made of astiff material such for instance as zinc or hard, stiff leather. To thetoe seam?) is situated at a predetermined distance from the tip of'thesole in 'orderto render the cutting of the edge possible, which isnecessary in order tov adjust the by-sole exactly to the bottom of *theshoe. In order to make it possible during walking to move the sole 2freely with relation to the by-sole, the'latter extends somewhat, beyondthe rear end of the sole 2-. Adjacent to the rear end of the sole 2 issecured a heel cap & of suitable height to give the necessary support tothe foot during walking. This heel cap is provided with lengthened sideportions 5 which embrace the foot and may be P o this sol the 'fieeilble$016 2 isfastened. The connectin connected to each other bymeans ofstrings or laces 6 over the ankle.

It will be understood that the by-sole i when correctly cut will lieimmovable in the boot just as if it was fastened to the bottom I of suchboot'o'r shoe, although it may be taken out and inserted into anothershoe of suitable length. If, for instance, the length of the foot is 26'centimeters the by-sole should have a length of approximatelycentimeters and should'extend 3 centimeters I to the front of and 1centimeter to the rear of the foot; The sole will then fit into a shoeof the proper size for such afoot.

- In the use of a device such as above described thefoot will occupy afixed position with relation to the shoe, so that neither toe nor heelwill come into contact with it, whereby the formation of blisters isprevented while at the; same time the natural mobility of the foot'ismaintained.

The foot may, of course, move inside of the shoe by reason. of itsanatomical natural joint connections without the use of an intermediatepart between the foot and the shoe 1 as above'described, but thismobility is combined with chafing and unnecessary straining of the foot,whereas by the use of this improved device the foot retains its freemobility without being subject to such straining or chafing, since iteffects the bending of only the flexible sole which is connected to thefoot, the by-sole and the shoe not follow ing the movementsof the foot.This involves alsoan easier Walk than without the inlay devicedescribed/ It is evident that the details of construc tion of the inlaydevice'may-be varied with out departing fromthe spirit and scope of A If7 10 Eric;

- the present invention. Forinstancepthe flexible sole may comprisemeansfor the connection between thefoot and the heel cap described andshown.

Having thus described my invention, what I claim is: 7

1. An inlay device for shoes, comprising a flexible sole, acomparativelyrigid sole connected tosaid flexible sole at the toe tip ofthe latter, and means for fastening said flexible sole to the foot ofthe wearer.

' QJAn'inlay device'as set forth in claim 1, the flexible sole beingprovided with aheel cap. v 1

3. An inlay'device as set forth in claim 2, the heel cap being providedwith elongated side parts adapted to be connected together over theankle of the wearer.

4. An inlay device as set forth in claim 1, the flexible sole beingconnected to the rigid sole at a predetermined distance fromthe toe tipof the latter.

5. An inlay device as setforth in claim 1, the heel portion of the rigidsole extending behind the heel portion of the flexible sole.

6. An inlay device as set forth in claim 1,.

the rigid sole extending beyond the flexible sole at both ends thereof.

7. An inlay device as set forth in claim 1, the flexible sole beingprovided with a heel cap having elongated side portions adapted to beconnected'together over the ankle of the wearer and the rigid soleextending beyond the flexiblesole at both ends thereof.

In testimony whereof I have signed my name to this specification.
